Taylor Swift‘s alleged stalker was arrested in Colorado last week on an outstanding warrant, giving us the first look at the guy who allegedly showed up at the singer’s home in possession of a knife, live ammunition, and black rope.

According to the Boulder County Sheriff’s Office, Julius Alexander Sandrock was arrested on April 20 at 5:50 PM local time. He was booked into the Boulder County Jail on a $500 cash bond.

He was released the same day.

Sandrock was on probation in Colorado when he was busted in Los Angeles outside of Swift’s home. The warrant stated that Sandrock violated his probation when he was arrested, by traveling out of the state, and because he skipped a drug test on April 8.

As The Blast first reported, police claim Sandrock “was observed attempting to enter the celebrity’s property while wearing a mask and rubber gloves.”
